Record Diesel Prices Are Raising Your Cost to Serve. Here Is What You Can Do.

Sygnal One Updated September 29, 2026 10 min read
Chart: the EU average diesel price hit a record €2.23 a litre on 21 September 2026, 45% up on a year ago and above the 2022 peak of €2.03. Since January, diesel is up 44% in the EU and 88% in the US, where it is at an all-time high.

Your transport costs are rising 10–15% in Europe and 20–25% in North America, from diesel alone.

It is not all bad news. There are things you can do.

Europe

The EU average hit €2.23 a litre on 21 September, up 44% since January and 45% on a year ago. Road freight contract rates were already 15% up year on year in Q2, before this spike.

North America

US on-highway diesel reached $6.53 a gallon the same week, an all-time high and up 88% since January. Surcharges reset weekly off the DOE index, so it flows straight into Q4 rates and RFP season.

Fuel is roughly 25–30% of the cost of a truck move. Apply that to the diesel rise and you get the range above. The only way to mitigate increases of this size is to leverage the intelligence in your business.

Why most shippers can’t see it

  • Fuel is handled differently per contract, country and carrier: a percentage here, cents per mile there, built into the base rate elsewhere.
  • Freight is often buried in a delivered price, so margin erodes without a transport line.
  • Surcharges lag the index, so the full hit lands next month.

Five questions to ask now

  1. Which customers and lanes have seen the biggest rise in cost per unit since January?
  2. How much of that is fuel, and how much is base rate, tolls or accessorials?
  3. Where freight is built into the price, does it still cover today’s cost to serve?
  4. Is the procured carrier base always being used, or is a lack of capacity forcing the use of more expensive carriers or the spot market?
  5. Which levers take kilometres or miles out: fuller trucks, consolidation, delivery frequency, mode?

It all starts with data

Shipment, cost and rate data connected across ERP, TMS and logistics partners, with fuel normalised across contracts, countries and regions. Once you have that, domain-trained AI can rank the levers by value and answer the questions above in seconds.

Record diesel is a cost nobody chose. Take control and mitigate these record prices.
